GEC will use energy modeling for analyzing design options and use as a value engineering tool for decision making as a part of integrated design approach. GEC will create energy simulation model and documentation as required in attaining LEED rating and to simulate and maximize energy credits. GEC will perform a building simulation of proposed design, and baseline to determine compliance with ASHRAE 90.1-1999; The model will also be used to optimize building energy performance by simulating various energy efficiency measure proposed by the design team. The number of runs to qualify the benefits of various energy efficiency measures will be determined and provided; the deliverable from this task will include energy cost savings due to various energy efficiency measures and LEED documentation for the energy efficiency points.
